. Application filed June ,19, 1922, serial 1\Tof5t9;321ak To all 'whom it may 00m-ern l Be it known that I, JOHN J. KRAUSE, citizen of Poland, residing at Portage, inthe county of CambriaI and State of Pennsylvania, have invented certain new and useful Improvements in Ship Sirens, of which the following is a specification.

rlhis invention relates to a ship siren, and it has for an object to provide a novel construction of siren adapted to revolve while sounding so as todirect the sound to all points of the compass.

Amore specific object of the invention is to provide a siren of this type which revolves unevenly so as to sound in a desired direction, such as int-o the wind, for a relatively long time. 4

For further comprehension of the invention, and of the objects and advantages thereof, references will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly-set forth,

Fig. 1 of the drawings is a side view of a Steamship, indicating my improved sirenv in position thereon. u

Fig. 2 is a part side view and part vertical sectional view of the siren.

' Fig. 3 is a fragmentary elevation showing the turbine.

Fig. 4 is a fragmentary elevational View, partly in vertical section, showing a modification. Referring now to the drawings the reference numeral 10 indicates a vertical pipe which may lead from a source of steam o r compressed air. Upon the upper end of this pipe 10 an internal gear 11 1s mounted for free rotation and has mounted in turn thereon the horn 12 of the siren, the upper end of the pipe 10 being provided with an 'ordinary sounding device 13 located in the spur pinion 23 meshing with the internall gear 11.I

As will be apparent, the steam or com pressed air fed through pipe 10 to the siren will rotatethe turbine wheel 16, causing the 'siren horn 12 to revolve around theupipe.

4In Fig. 4 I have shown a modification y adapted to cause `an uneven revolution of the horn 12, so that the latter may sound for a relatively longertime when pointed in any selected direction.

In'this arrangement the has ad? 'l justably fixed thereto as the set screw 25,v at a point just above the turbine 15, a camy disk 26 engagedby al second camdisk' 27 fixed on the lower end of a sleeve 28 freelylsurrounding the pipe 10. The upper por'- tion of the bore of this sleeve `28 is larger than the pipe to receivethe lower end of a second sleeve 30 also freely surrounding the pipe 10 toy be rotatable thereon, but being held against axial movement by suitable engagement at its upper end with a collar 31 fixed to the pipe. Fixedto thesleeve 30 is a diskv32 on which i 1s mounted the horn 12, the pipe havingthe sounding element 13 on its upper end. F eathered, as' at 33 upon the sleeve 28 is a i gear `34 which engages thepinion 23 on the upper end of shaft 20. This gear 34 is held f against axial movement between a pair of fixed bearing elements 35." The cam disks 26, 27 are normally pressed together by al spring 37 bearing between the horn-carrying 28 has a drive connection with'the sleeve 30 by means of a pin 40 carried by the former and engaging in a spiral slot 41 in the latter.

In the operation of this form of the de vice, as gear 34 is rotated by pinion 23 it rotates sleeve 28 which latter rotates the sleeve 30, through the medium of pin 40 engaging in the slot 411. -As sleeve 28 rotates it is moved longitudinally by reason of cam disk 27 vriding over the fixed cam disk 26 and because of the spiral dispositionof slot 41, causes the sleeve 30 and in consequence the horn 12 to revolve at varying speeds during different portions of eachl revolution. By loosening set screw 25the cam disk 26 may be adjusted so as to cause the retardation of the revolving movement to take place as the horn is pointing'in any desired direction. e

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United Statesis as follows:-` H t 1. A siren for ships comprising a revolu- 'disk 32 and the top. of sleeve 28. 'The sleeve vbly `mounted horn, a sounding device therein,

a cylindrical member fixed to andv extending axially ofk said horn and having a spiral slot m the side thereof, a sleeve surrounding said member and having a spin, engaging insa-id y slot, means for rotating said sleeve, and means 'formovlng 1t axially.

2. A siren Jfor ships Comprising a revolu- V bly mounted horn, a sounding device therein,

a cylindrical member fixed to and extending axially of said horn and having a spiral slot in the side thereof,` a sleeve surrounding on oneend o'rsaid sleevey bearing on l f said stationary cam, and a spring pressing against said sleeve. Y

3.'A siren for ships comprising a pipe, a

`sleeve ixed to said horn and surroundingsaid pipe, a "secondsleeve freely surrounding the pipe and having telescopic engagement With said first sleeve, one of said sleeves having a fixed pin engaging in a spiral slot in the' other sleevevvhereby the second sleeve rotates the first, co-operating cam disks fixed respectively on saidseeond sleeve and `said pipe, a gear having a feathered engagement With said second sleeve, a turbine adapted to be drivenby fluid passing through said pipe, and drive conneetions betiveen'sai-d turbine and gear.' 7 I 'f ln testimony whereof I have aiii'xedmy signature. v
